IMPROVEMENT IN BED-BOTTOMS.

g Specicatioufor-ming part of Letters Patent No. 126,801, dated May 14, 1872.

`and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to makeand use the same,reference being had to the accompanying drawing forming part of this specilication, in which drawing- Figure l represents an end view of my invention, partly in section. Fig. 2 is a longitudinal vertical section ofthe same.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of tension-spring levers bearing on the corners of the webbing which forms the connection between the slats and helicenical springs in such a manner that, by the .action of said tensionspring levers, the webbing is always kept tight, the heli-conical springs are retained in an npright position, andthe end slats are prevented from assuming an outwardly-inclined position when the bed is used, thereby preserving the fullwidth of the bed in an effective state. Vth the heli-conical springs, tension-sprin g levers, and the slats, are combined cylindrical plugs provided with grooves or recesses just large enough to receive the small ends of said springs, in such a manner that when the plugs are secured to the slats and the small ends of the springs are sprung into their recesses a firm connection is produced between the slats and the spring in a simple, cheap, and durable way.

1n the drawing, the letter A designates the frame of my bed-bottom, the transverse bars a of which form the supports for the heli-conical springs B. These springs are connected at their top ends by a piece of webbing, C, which is secured to the traverses a, and this ywebbing is exposed to the action of tensionspring levers b, which are secured to the traverses, and bear against the webbing just beyond the end springs B, as shown in Fig. 1. By the action ofthe tension-spring levers the webbing is kept taut, and the heli-conical springs are prevented from tipping over. The outer ends of the springs-levers b are or may be provided with friction-rollers, to reduce the wear of the webbing. On the heli-conical springs B are placed the slats D, and if a person lies down on the bed the end slats are prevented from assuiuing an outwardly inclined position, since the tension-sprin g levers b turn their outer edges up, and thereby the full effective area of the bed is preserved. If the tension-spring levers are omitted the end slats incline outward, and the ei'ective area of the bed is reduced by the full Width of the two end slats. The connection between the slats D, the webbing C, and the heli-conical springs B, is effected by means of plugs c, which are fastened to the slats by nails, screws, or other suitable means, the webbing being placed between them and the slats. These plugs are provided with recesses d just large enough to receive the small end coils ot' the springs B. If these end coils are sprung into the recesses of the plugs a rm connection is effected between the slats and the springs, and, if desired, the springs can be readily disconnected. v

Whatl claim as new, andV desire to secure by Letters Patent, is-

1. The tension-spring levers b, in combination with the webbing C and slats D, substantially as described. Y l 2. The combination of the springs B, tensionspring levers b b, and plugs c c, slats D, and webbing C, arranged and operating substantially as described.
